At the risk of sounding like I know nothing (because its true) what is MBA? My computer says there are no updates available, iTunes and my iPhone 5 are running at their most current available systems. I have still tried many times to open the settings for syncing my iPhone in iTunes, selecting "sync all calendars" and it has yet to work.
I'm operating on OS-X 10.6.8 and it says that is the most current available to my computer. Apparently it can't "handle" anything beyond that, although there is plenty of memory left on it.
Maybe I should swear at it some more? I'll try that.

It took some time, but I found this and it worked! Whew.... This is such a common glitch you'd think Apple would have a fix for it by now. Anyway, here is what I found and it's all good now, hope it helps someone else. (Courtesy of this website:http://iphonewriter.blogspot.co.nz/2008/05/how-to-fixing-ical-iphone-sync-issues .html)
"You'll know the syncing issue when you see it, because the new events you enter into the Calendar on your Apple iPhone will not appear in iCal. Said another way, you'll enter a new event into your iPhone, use iTunes to sync with your Mac (or MacBook in our case) and the new event on your iPhone will not show up in iCal. Keep trying, synch as you might, iCal and the Apple iPhone just won't get along.
Here's the down and dirty fix:
That's it! You should be all set and iTunes, iCal and our Apple iPhone should all be playing nicely as friends again. We've used the exact method to repair our own Apple iPhone at least once... maybe even twice."
